How does it work

Vue Js comes with a reactivity system. As a first step, you create a Vue instance. During the instantiation of Vue, you create some properties. When you define a data property (specific property of the Vue object) Vue creates getters and setters for it. These are JavaScript functions bound to a JavaScript object, whose purpose is to dynamically return a computed value and to find changes dynamically in a specified property. 

Benefits of Vue, js

  • Lightweight – Smaller than other libraries of Javascript
  • Performance – High speed and faster performance are guaranteed
  • Flexible – Developers can choose how to create templates, whether it is an HTML or Javascript files
  • Thriving community – It has a growing community

Key concept of Vue.js

  • Virtual DOM – VDOM is the speciality of the framework’s rendering system. When modification is required modifications are used by forming a new javascript object.
  • Data Binding – Changing the attribute value dynamically easy peasy with V- bind, the binding directive.
  • Components – Components are not at all dependent elements in Vuejs that allow the division of user interfaces into reusable pieces so that developers can work on them as silos. When you create a new element with a component, it can be used multiple times in HTML.
  • Event Handling – The Event handler value can be either method handlers or inline handlers and Vuejs use the V-on directive property in DOM.
  • Transition – The transition component is a built-in component of Vuejs that lets automatic addition or removal of CSS classes to trigger animation as per the changes in DOM. Vue.js also has a <TransitionGroup> component that can apply animations when an element or component is inserted into, removed from, or moved within a v-for list. You can even add third-party elements.
  • Templates – HTML templates can be used by web developers to declaratively bind DOM.
  • Directives – All in all front-end tasks can be carried out using directives. There are many directives in Vuejs.
  • Routing – If you want to navigate elements in single-page applications Vue -the router is the only option you have.
